♣I have recently discovered BBO tournaments and would like to thank
the owners and developers for providing the feature.

The experience is worthy of a grade of 99.9 and any comments are only
meant to see if it might be possible to nudge it another few 1/100ths
of a grade-point upward.

I did wonder about the robots's bidding as South in the following:

---

I had no idea what 4♣ meant. I did not think it could be Gerber, but
could not decide if it was a cue bid or natural and finally chose 5♣
as being good as any given my confusion. Pass after the robot's 5♠
was just hoping for the best, and it worked out since I botched the
play making only 11 tricks while 6/9 others made 12 or 13, although
only one bid slam.

But getting back to the 4♣, was it Gerber after all, since it seems hard
to justify as a cue bid? If so I cannot find Gerber in the BBO advanced
system notes except after a 1NT opening. Have I missed it there or elsewhere?

4♣ in this sequence is:
!Splinter -- 1- C; 3+ D; 4+ S; 21- HCP; 19-22 total points

While playing with GIB as partner pointing the GIB's bid will provide you with the information that bid carries.
Same would be done while you're picking bid from the bidding area. A window with an explanation will be pop up to hint you if consider what your bid is promising.

Thank you for the helpful explanation, and for the tip on using the pointer on GIB bids.
